Blanks

Ceramic blanks with ready-made layer connections

PewCB uses two-sided PCB blanks with an integrated via grid and rows of plated through-holes along the edges. This solves one of the biggest challenges in desktop fabrication: creating reliable interlayer connections. PCB blanks range from 23 × 23 mm to 84 × 84 mm.

Use the provided blank templates in your eCAD software, route traces to the nearest available via to switch layers, and place through-hole parts in available PTHs—completely skipping drilling, chemical processing, or electroplating.

Blank construction

PewCB ceramic PCB blank showing the solder mask, copper foil, ceramic substrate, and a cross-section of a plated via connecting both sides — Blank construction. The via grid and peripheral holes shown belong to the first-generation design; use the template for your selected blank revision.

Pre-Fabricated Vias

Factory-made plated vias connect the top and bottom copper layers. Route layer changes to the nearest available via, without drilling or plating new connections during fabrication.

Copper

The copper is 18 µm foil, not a thin printed or deposited layer. It is firmly bonded to the ceramic, so traces and pads stay attached during soldering and rework.

Solder Mask

The laser opens the component pads and leaves the trace tops protected. The pictured blanks use red mask on top and blue on the bottom, making the two sides easy to identify.

Ceramic Substrate

Alumina withstands laser processing and soldering temperatures. Its high thermal conductivity spreads heat through the board during hot-plate or oven reflow.

Peripheral through-holes

First-generation blanks have plated hole rows on a 2.54 mm pitch for common connectors and through-hole components. These holes can also serve as extra connections between layers.

Repeatable mounting

Corner holes locate the blank on the tray’s mounting pins. Flip it onto the same pins to process the second side. The matching template keeps the circuit aligned with this mounting geometry.

Outlines & panels

Cut an outline.
Or assemble, then snap apart.

The laser can also cut the ceramic: custom outlines, cutouts, and holes that do not have to be round. V-scoring keeps a panel together for paste, placement, and reflow, then lets you separate the boards by hand.
